Is it ok to start a blu ray collection now?

I started a collection Blu-ray. Its small but. However, I am hesitant to increase my collection of Blu-ray mainly due to the fact that 3D Blu-rays reach the market soon.

Hmm ....
Good question.
3D BluRay discs will be made to select movies.
It will not be used to --- 3D is synthesized for hours and hours of layer-mastering.
